Going without beef burgers is not going to impact the climate anywhere near as much as some like to claim. This is even confirmed by the IPCC (see below).
Climate alarmists and closet vegetarians like to claim that methane produced by cows plays a huge role in climate change, and so people need to eat much less beef and other meats from ruminants. Bill Gates even wants people to turn to fake, “synthetic meats”. But it’s all mostly hype and hysteria.
